- Cheapest overall: Nordic spruce feather edge — from £20–£30 per m². Requires treatment every 2–3 years.
- Cheapest naturally durable: Siberian larch feather edge — from £35–£50 per m². No treatment needed.
- Cheapest profile in any species: Feather edge — least machining, lowest waste, lowest price.
- Whole-life cost warning: The cheapest upfront option is rarely the cheapest over 20–30 years — untreated spruce that fails early costs far more than larch that lasts without maintenance.
- Best budget strategy: Use spruce on sheltered or rear elevations; larch on primary visible elevations.
Everyone wants good value on timber cladding — but cheap and good value are not the same thing. The cheapest cladding upfront can become the most expensive cladding over 10–20 years if the wrong species is specified for the exposure, or if maintenance obligations are not met. This guide gives you an honest breakdown of the genuinely affordable timber cladding options in the UK in 2026 — what they cost, what they require, where they work well, and where the hidden costs lie.
Timber cladding does not need to be expensive to look good and perform well — the right species and profile choice at the right price point delivers excellent results for garden rooms, extensions, and sheds across the UK.
Upfront Cost vs Whole-Life Cost — The Most Important Distinction
Natural timber grain — the honest beauty of timber cladding at any price point. The key decision is not just how much it costs upfront but how much it will cost to maintain or replace over the life of the building.
Before ranking options by price, it is worth being honest about what cheapest actually means in the context of exterior timber cladding. A £20 per m² Nordic spruce feather edge board that requires replacement in 8 years because it was never treated is not cheap — it is expensive. A £50 per m² Siberian larch feather edge board that performs for 30 years with no treatment at all is genuinely cheap over that period.
The upfront material cost is only one part of the total cost of ownership. For any timber cladding project, the real cost calculation includes the upfront material cost, the treatment cost over the service life (how many applications, how much product, how much labour), any repair or board replacement costs during the service life, and the cost of eventual removal and replacement. When all of these are factored in, Siberian larch is almost always cheaper than Nordic spruce over 20 years, and ThermoWood is often comparable to larch despite its higher upfront cost.
Specifying cheap untreated softwood (construction grade pine or spruce) as exterior cladding without a proper preservative treatment and maintenance schedule. Untreated softwood in above-ground UK exterior use begins to show biological decay within 3–5 years and typically requires full replacement within 8–12 years. The cost of removal and replacement — including scaffolding, disposal, and new materials — invariably exceeds the saving made on the original cheaper specification.

Whole-Life Cost Comparison — Where Cheap Gets Expensive
Naturally weathered Siberian larch cladding — the silver-grey patina develops without any treatment or maintenance cost. Over 30 years, larch costs significantly less in total than treated spruce despite the higher upfront price.
The table below shows the approximate whole-life cost per m² over 30 years for a typical UK exterior cladding project, including upfront materials, treatment products and labour over the service life, and a proportional allowance for eventual replacement.
| Species / profile | Upfront cost/m² | 30-yr maintenance/m² | 30-yr total/m² |
|---|---|---|---|
| Spruce feather edge — maintained | £20–£30 | £45–£75 (10 treatments) | £65–£105 |
| Spruce feather edge — unmaintained | £20–£30 | £80–£150 (early replacement + scaffold) | £100–£180 |
| Siberian larch feather edge | £35–£50 | £0–£15 (optional oiling) | £35–£65 |
| Siberian larch shadow gap | £45–£65 | £0–£15 (optional oiling) | £45–£80 |
| ThermoWood shiplap | £55–£75 | £0 | £55–£75 |
A maintained Nordic spruce installation costs approximately £65–£105 per m² over 30 years — comparable to or more expensive than Siberian larch at £35–£65 per m² over the same period. An unmaintained spruce installation — by far the most common outcome — costs £100–£180 per m² once early replacement costs are factored in. Siberian larch feather edge at £35–£50 per m² is genuinely the best budget cladding in the UK when whole-life cost is the measure.
Where to Save — Practical Budget Strategies
Shadow gap profile on a garden room — a contemporary result does not require a premium species. Siberian larch shadow gap at £45–£65 per m² delivers the same architectural profile as ThermoWood at a significantly lower upfront cost, with no maintenance requirement.
1 — Choose feather edge or shiplap over shadow gap
In any species, feather edge is the cheapest profile — it requires the least machining and produces the least waste in production. Shiplap is the next most affordable. Switching from shadow gap to shiplap in Siberian larch saves approximately £7–£10 per m² — on an 80m² house that is a saving of £560–£800 on materials alone, with identical performance and natural durability.
2 — Mix species by elevation
Use Siberian larch on primary visible elevations (front and sides) where appearance and durability matter most, and Nordic spruce on rear or sheltered elevations where the building is less visible and maintenance access is easier. This approach can reduce material costs by 20–30% on a full house while keeping the main elevations in a naturally durable, maintenance-free species.
3 — Order full pack quantities
Timber cladding is priced significantly more cheaply when ordered in full pack quantities rather than cut packs. If your project is close to a full pack quantity, rounding up slightly to avoid the cut-pack premium almost always saves money overall — the excess boards can be stored for future repairs. Contact our team for current pack sizes and quantities before ordering.
4 — Self-install
Installation labour typically accounts for 30–40% of the total installed cost of timber cladding. For competent self-builders, self-installing saves £25–£45 per m² — on a typical garden room this is a saving of £625–£1,125. For a full self-install guide see our how to clad a garden room guide and our timber cladding installation guide.
5 — Avoid peak season
Spring and early summer installation slots attract a premium from most cladding contractors. Late autumn and winter installations — when demand is lower — often come in 10–20% cheaper on labour. Material costs are consistent year-round.
What to Avoid — False Economies in Cheap Cladding
Long-term weathered result on a correctly specified garden room — timber cladding specified and installed correctly looks attractive and performs reliably for decades. The false economies below turn a low upfront cost into a high total cost.
- Untreated construction softwood — standard C16/C24 framing timber sold as cladding is not intended for exterior use and has no durability treatment. It will fail within 3–5 years in exterior exposure
- Cheap galvanised fixings — saving £20 on fixings by using galvanised rather than A4 stainless steel leads to rust staining within 2 years and fixing failure over time. Always use A4 stainless
- No breather membrane — omitting the membrane saves approximately £2–£4 per m² but risks structural frame decay that costs thousands to remedy
- Skipping end grain sealing — a £15 tin of end grain sealer protects every cut end. Without it, moisture enters at cut ends, causing splits and early deterioration
- Nordic spruce with no maintenance plan — only specify spruce if there is a genuine commitment to treating it every 2–3 years. Without treatment, it will fail far earlier than larch at comparable or greater whole-life cost
What is the cheapest timber cladding in the UK?
Nordic spruce feather edge at £20–£30 per m² is the cheapest timber cladding in the UK upfront. However Siberian larch feather edge at £35–£50 per m² is cheaper over a 20–30 year period because it requires no ongoing preservative treatment — making it the best budget cladding on a whole-life cost basis.
Is cheap timber cladding worth it?
It depends on the project and whether maintenance will genuinely be maintained. Nordic spruce is worth it for temporary structures, budget sheds, or projects with a committed maintenance schedule. For permanent buildings where maintenance is unlikely to be kept up, the upfront saving is typically lost within 10–15 years through treatment costs or early replacement.
What is the cheapest cladding profile?
Feather edge is the cheapest profile in most timber species — it requires the least machining and wastes the least timber. Nordic spruce feather edge at £20–£30 per m² is the cheapest profile overall. Shiplap is the next most affordable, followed by loglap, then shadow gap.
How can I reduce the cost of timber cladding?
The most effective ways: choose feather edge or shiplap over shadow gap; use spruce on rear elevations and larch on front; order in full pack quantities; self-install rather than using a contractor; and book installation in late autumn or winter when labour rates are lower.
What is the cheapest naturally durable timber cladding?
Siberian larch feather edge at £35–£50 per m² is the cheapest naturally durable timber cladding in the UK — no preservative treatment required throughout its 20–35 year service life. Despite being more expensive upfront than Nordic spruce, it is cheaper over a 20+ year period for most projects.
